Weird MacOS mouse glitch

No, I didn’t restore anything. I have erased my entire drive, did a clean install of MacOS Ventura.

So at that point you should have seen a prompt to create a user account, the primary admin one with UID 501, choose your user name & password, etc., right? At that point, what did your Home folder look like as far as the contents of its various folders? Music, Movies, Pictures, Documents, & so on if automatically created should be empty. ~/Library/Application Support should have nothing in it related to Affinity, & nothing related to any app that isn't installed automatically along with the OS.

And after installing AD v2 that should be the only app in the root level Applications folder, other than the Apple apps that come with the OS.

Is that what you did & does it match what is described above regarding folder contents?

Yes, I have created a new user account with a new username and password. At this point I cannot tell you the contents of those folders right after I reinstalled my os, because I didn't check them. But my documents folders were empty, I had to manually copy all my files, music, fonts, projects - everything - from my external drive, which I did later on after I confirmed that the issue mentioned in this thread continues to happen.

I have spent my entire weekend testing thousands of combinations and correlations trying to replicate this issue and find a reason behind it and.. I think I did, and it's a dumb one.

It happens right after I save the file I'm working on. For example, I press ⌘+S and then I try to move something and then it glitches as described in this thread. I don't know why, but I never noticed it before, I thought it's kind of random. I've played with it for entire day and I'm 100% sure that's when it happens. Today I changed the keyboard shortcut to save files so my muscle memory wouldn't try to force me to save files and that's the workaround that works for me. It's annoying and I hope I won't lose any progress when I forget to save a file with a new keybind, but hey, at least the designer is usable again.

Are you saying that you can save & continue without this issue recurring if you just avoid using the original ⌘+S keyboard shortcut, so for example if you use the File > Save menu item or your new shortcut to save everything works OK?

If so, that is really weird & I cannot imagine wht how you invoke a save would have any effect like this.

No, I mean that saving in any way or form causes this issue. I changed the default keybind so I would stop saving constantly as it's my habit. I'm sorry if this wasn't clear, English is my third language.

This sounds indeed strange, as if a "Save" action keeps AD busy in the background, e.g. to finalize its communication between the .autosave and the (overwritten) document file on disk and thus causing a delay in mouse move rendering on screen. (although, you mentioned the cursor's offset jumps as extra entries in the History panel, which makes it more weird)

• Does it make a difference if you choose "Save As…" with a different file name to create an entirely new file on disk?

• Does the storage location have any influence?

• In case it is activated: Does it matter if you have Time Machine backups & its hourly snapshots deactivated in the macOS system prefs?
